1598961743 M * Ghislain on the vserver patch there is quite some btrfs patching, i guess this is for the tagging but there is also line for "sync_flags", is it related to tagging also ? so if no tagging then btrfs or zfs or others are fine ?
1598962532 N * Bertl_zZ Bertl
1598962536 M * Bertl  morning folks!
1598962608 M * Ghislain hi bertl
1598962680 M * Ghislain i try 4.9.234 and  got 2 easy reject, one is the self.c comment, the other is an include order in timer.h, it's compiling for the moment
1598962695 M * Ghislain was wondering about the btrfs part of the patch
1598962708 M * Bertl filesystems are usually fine, as long as you do not need any of the special filesystem features
1598962727 M * Bertl like cow link breaking, barriers or quota
1598962734 M * Ghislain if i remember correctly my last test showed testfs working only on ext4 and failing on xfs and others
1598962737 M * Ghislain ok thanks
1598962766 M * Ghislain if it fails on btrfs and xfs, is  tagging still working on those ?
1598962768 M * Bertl filesystems which have their own group/project quota should be fine as well
1598962814 M * Bertl I'd have to check, IIRC we never implemented tagging on btrfs and we removed it some time ago from xfs
1598962857 M * Ghislain there is some patching in the btrfs tree done but not in xfs
1598962882 M * Bertl most likely attributes
1598962900 M * Ghislain it add a tag to the structure
1598962926 M * Ghislain and some  sync_flags
1598963403 M * Bertl ah, maybe we did full tagging back then
1598966585 M * Ghislain which namespace do vserver use ? pid and network (if configured that way)  i think ? do it use UTS,ipc etc.. ?
1598966638 M * Ghislain oh there is a timespace also that can replace the virtualisation of the time since  5.6
1598966642 M * Ghislain where does it end :)
1598966648 M * Guy- uts certainly
1598966746 M * Ghislain in the patch i see mnt uts ipc and pid also
1598966827 M * Guy- yes, those too
1598966970 M * Ghislain ok so i see the only one missing is the user but i think this one would wreak havock in the vserver system
1598966993 M * Ghislain also i dont know how the "i am gROOT" problem in the guest would work :)
1598967894 M * Ghislain apart from the 2 rej i got 4.9.234 running testfs ext4 ok, testme ok : https://pastebin.com/raw/v109NGfc
1598968100 M * Guy- Ghislain: too bad you can't trigger the arekm bug
1598968165 M * Ghislain yep last time i tried it did not trigger. It is using network namespace ?
1598968168 M * Ghislain i dont remember
1598968292 M * Ghislain on xfs testfs fail: tag related tests ...
1598968292 M * Ghislain mount: /mnt: wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error.
1598968292 M * Ghislain [011]# failed.
1598968332 M * Guy- Ghislain: no, it's related to policy routing
1598968341 M * Guy- I also can't trigger it on all boxes
1598968413 M * Ghislain oh ok
1598968423 M * Ghislain on xfs if i remove the -x i got https://pastebin.com/raw/tDYVmftn
1598968767 M * Ghislain FYI
1598970835 M * Bertl so the flags do not work as expected there
1598970877 M * Bertl i.e. barrier is not retained, instead we seem to end up with an immutable flag there
1598970910 M * Bertl immutable unlink (link inversion) is also not working
1598970943 M * Bertl if you do not need either, you are definitely fine
1598975334 M * Ghislain ok, i dont find any ref to xfs in the patch so i think it is like zfs or others non supported FS
1598975355 M * Ghislain you can use them but you dont have shared files ,and quotas/limits
1598975388 M * Ghislain i think the only fs that support real cgroup scheduling is btrfs, thats a shame :)
1598975647 M * Ghislain so for a FS with cgroup scheduling, quota and advanced features we have btrfs, then zfs with no cgroup scheduling, then xfs with a few scheduling i think for metadata
1598975695 M * Ghislain but quota is per directory not user/group
